Help with New Zealand shopping please???

Do any New Zealand mumsnetters (or anyone else for that matter ) know of a good online DVD site. I want to send a DVD as a birthday pressie to New Zealand but don't know where to get one from. Most of the ones I usually buy from don't have many, if any, Region 4 DVD's.
I googled but don't know if the ones it brings up are any good or not!
